finding a flat when you arrive is very easy. the university has a partnership with student residences all over the city. it's TOAS. with this you are bound to get a flat.
There are two types of accommodation, shared flats where you will be 2 or 3 students of the same sex. you will have a kitchen and a shower for your flat. you will also have a gym, a sauna and washing machines available for all the people in the building.
the second type is to have a room in a student residence where you will only have a shower for yourself. the rest will be shared.
The prices are very affordable, but sharing is more expensive than a room in a student residence.
You can also find accommodation without using TOAS, but this is more complicated and directly more expensive.
